This inventionrelates to mechanism normally operated from a keyboard andhas for its object to provide a simple method and means of connectingtwo such machines so that the operation of the keyboard on the onemachine is caused to operate a second or other machine connected to themachine of which a keyboard is operated, particularly with the object ofincorporating in each machine such mechanism as will enable the actualconnection between the machines tov be of the simplest possible nature.I

' Another object is to connect a typewriter withvanother normally keyoperated machine such as a perforator, and a further object is toconnect relay opera-ted machines, such as typewriters to punch machinessuch as are employed for perforating statistical record cards. y

In the connection of machines which have keyboards of equal size it is asimple matter to provide connections from the keys of the one machinetothe keyboard of the other, but where the keyboard of one machine is 5larger than the keyboard of another it is necessary to utilizecombinations of keys on the smaller keyboard in order to producein themachine with the smaller keyboard all the ciphers of the largerkeyboard.

One way of connecting a larger keyboard to a smaller keyboard is todirectly connect the keys of the smaller keyboard and then to employ twoconnections from each of the other keys on the larger keyboard so thateach of the keys on the larger keyboard in excess of the keyson-thesmaller keyboard has connections to the smaller keyboardcorresponding tothe code employed. 7 If the combination of two keys on a smallerkeyboard are utilized to represent keys on the larger keyboard in excessof the keys on the smaller keyboard there will have to be twoconnections for each such excess keys.v

in accordance with the present invention, the keys of the smallerkeyboard or extenr sions thereoi are CllSPOSGCl across the keysorextensions thereof of the larger keyboard and selecting devices areemployed on 'the' tively.

larger keyboard in excess of the keys on the smaller keyboard directlyselects the desired combination in the smaller keyboard.

In order that the nature of this. part of the invention-may be moreclearly understood an example of the employment of the invention as ameans of connecting the keyboard of a typewriter to a keyboard of astatistical card punching machine will now be ;'described. a V I -1 4 rI The keyboard of a punching machine comprises but twelve numeral keys.and thekeyboard of an ordinary typewriter. twenty-six alphabetical keys,and ten numeral keys.

, Now it is desired-to connect the alphabetical keys of the typewriterto the keys on the punching machine, so that a card will be perforatedaccording to a code in which but the twelve keys are used individuallyor combined to perforatethe card in a single column to represent all theletters of the alphabet. I Such a code is in itself well known and isgenerally stated to comprise the employment of one key with each ofthevothers toattain the desired selective combinations. One suchcodeisas 'followskv f-i A The key 12 represents the letters Z and X. Thekeys, 11,.0,,1 2, 3, 4, 5, and6 represent respectively the letters A toH, the key 7 the letters I or J, the keys 8and 9 respectively .theletters K and L. Then to obtain the re maining letters ofthe alphabetcombinations such as the following are chosen v V The keys 12 and 11 areused for the letter ,The keys-12 and 0 for the letter N and the key 12is used with the letters 1 to 6 to produce the letters 0 to Trespectively. The keys 12 and 7 are employed to prepresent the lettersUor V and the key 12 withthe keys S V respecf and 9 to represent theletters W and Y To connect keyboard with theialphabetical keys ofatypewriter the typewriter keys are provided with displaceable, forinstance, hinged 'members, one member forv each key; and in a planelying across the 'displa ce- ,able members and in. juxtaposed positionthereto are arranged members, for instance,

bars which are moved by the displaceable mem'berswhen moved about theirhinges.

The machine having the large keyboard may conveniently be referred to asthe master machlne and the punching machine may conveniently be referredto as the servant machine. Then it may be stated that the depression ofa key on the master machine, causes through suitable intermediatemechanism, a rocking of a hinged member (all of which are preferablyarranged in one plane) into engagement by the hinged member of the baror bars corresponding to the keys of the servant machine.

Each of the bars corresponding to the keys of the servant machine isprovided with a selector device so that the hinged member of the mastermachine moves only the bars of the servant machine corresponding to thealphabetical key depressed. To this end each bar may be provided withadjustable sliding members disposed and arranged so that each hingedmember engages only the bar or bars required to be selected to operatethe servant machine.

Where the combination is definitely known, the selector members may be,in fact, fixed members, for instance, lugs integrally formed with thebars.

In the employment of the code already stated, the bar corresponding tothe key 12 on the servant machine will have a selector lug forconnecting up the hinged member of the key Z and another lug forengagement on op eration of the key X. There will also be on the bar ofthe key 12 of the servant machine a lug for operation by the hingedmember of the keys M to Y so that the bar corresponding to the key 12 ismoved as a result of depressing any one of the said letters of thealphabet but hinged members operated as a result of depressing thealphabtical keys M to Y will also engage the lugs on the barsrepresenting the numerical keys on the servant machine, 11, 0, 1 to 9,to produce the combination above stated.

The bar 11 will be provided with a lug for operation by the hingedmember of the key A of the master machine and the bars 0 to 9 will havelugs spaced in staggered rela-' tion for engagement by the hingedmembers corresponding to the alphabetical keys of the master machine Bto L.

In such an arrangement there are only as many connections as there arekeys. on the keyboard, the hinged members being, in fact, extensions ofthe keys on the master machine and the bars being extensions of the keyson the servant machine. These two sets of members lie across one anotherand the lugs above mentioned provide the selector devices.

Generally speaking, it is convenient to arrange the bars at right an lesto the hinged members but another smaller angle may be employedaccording to the design of the connection required.

Conveniently, each of the bars corresponding to the keys of the servantmachine are part of a parallel ruler system so that a similardisplacement of the bar occurs wherever the selector lug is disposed inother words, whatever part of the bar is engaged by a hinged member.This lateral movement of the bar may conveniently be employed to producelongitudinal displacement of a. rod the ends of which in turn formactuating plungers of a flexible means, for instance, a Bowden mechanismcommunicating the effort to the setting devices of the punching machine.

This invention may be carried out in various ways, but one construct-ionaccording thereto is diagrammatically illustrated by way of example inthe accompanying drawings in its application to a relay operatedtypewriter for instance, a Mercedes machine, which is coupled to a relayoperated punching machine.

In the drawings Fig. 1 illustrates in perspective the translat-ingdevice and the mechanism associated with one-key of the punchingmachine;

Fig. 1A is a detailed perspective View of a part of the translatingdevice shown in Fig. 1.

Fig. 2 is a cross sectional elevation of the typewriter showing the keyactuated type mechanism and the translating device;

Figs. 3 and a are respectively a rear elevation and a plan of thetranslating device;

Fig. 5 illustrates the connection between the back spacing key on thetypewriter and the translating device, and

Fig. 6 shows the connection between the space bar on the typewriter andthe translating device.

In the construction illustrated in the drawings the typewriter comprisesfor each key 1 a key bar 2 extending inwardly of the machinesubstantially in a horizontal position and carrying a vertical latchmember '3 normally lying over a lug 4 on an arm 5 hinged to a pivotedintermediate lever 6, the arm being held in substantially horizontalposition by a spring 7 and carrying a nose 8 which is brought intoengagement with a continuously rotated toothed member 9 usu allyreferred to as a. roller, as a result of the catch 3 pulling the arm 5down by engaging over the lug tt when the key bar 2 is rocked downwardlyas a result of depressing the key 1.-

As a result of bringing'down the arm 5 causing the nose 8 to engage withthe roller 9, the arm is brought forward by the roller rotating and thearm coming forward rocks the intermediate lever 6 about its pivot thislever being connected with lost motion to a type bar 10. Thereby thetype is brought into operative relation with the platen of the machine(not shown). 7

New in order to connect this sort of machine to a statistical cardperforating machine, for instance, as described in Thomas U. S. patentapplication Serial No. 419,974,

the intermediate lever 6 of the typewriter may be extended convenientlybelowits pivot to provide an operative rocking extension member 6a movedas a result of depressing the respective key. J

In association with the extension 6a of the intermediate lever apush-trod 12 may be employed and at theback of the machine convenientlyinthe form of a'unit'structure is arranged a frame'carrying verticaldepending hinged members 13 one for each push rod 12, that is to say,one for each alphabetical and numeral key of the typewriter, the framecarrying on its lower part twelve horizontally disposed laterallymovable bars l lserving to operate rods 16 the ends of which are guidedin. a plate or bracket 17 "carried by the unit structure.

Each bar His connected to its operating rod 16 by means of a parallelruler mechanism comprising bell cranks 15 and 15a connecting theparallel bars 14: with corresponding bars 14a. The operating rods 16 areconnected to the bell cranks 15 so that when a bar 14- is movedlaterally, the corresponding bell crank 15 also moves and actuates the 7rod 16.

The pushrods 12 may abut directly against the intermediate members 13 asindicated at 1260 in Fig. 2, but in some cases, it'is desire able toprovide a reducing lever system between the push rod and the lever 13.'To this end the push rod may abut against a finger 13a of a plate 13?)carrying'a pin 130 which in turn abuts against the end ofthe hingedmember 13. The plate 136 is pivoted at l3cland the push rod'1 2 abutsagainst the finger 13a at a greater radial distance from the centre 13dthan the radial distance be tween the pin 13c and the centre 13d. i

A translating device comprising hinged members and displacealole barsaccording to the invention disposed as above described permits the dualoperations to be performed without any additional service whatever beingthrown on the keys of the master machine. The additional work is done bythe power operated rollers.

Each hinged member 13 abuts against a lug '18 on one or more of the bars14 in accordance with the code to be used; For example, the hingedmember 13 corresponding to the key A of the typewriter will engage withthe lug 18 on the bar 14 corresponding to the setting member for thepunching machine which is adapted to perforate a hole in the 11 positionon the card, whereas, as already explained the bar corresponding to thekey 12 on the servant machine will have a lug 18 against which bears thehinged member corresponding to the key Z on the type writer and alsoanother lug for engagement with the hinged In order to prevent confusionin'Fig. 1 only two bars have been illustrated and it will be seen thatthe hinged member 13 to the extreme left of the figure, engages with alug 18 on one bar only, whereas the hinged member in the centre of thefigure, engages -with lugs 18 on twoof the :bars.

gages a'lug 18 on one of the bars 14 arranged corresponding to the code,e. g. such as already explained. Therebya particular bar is displacedlaterally and the end of the oper dating rod 16 projected through theguide plate 17 at the end of the structure. The structure may includecombplates 19 for maintaining the hingedmembers separate from oneanotherand for locating them accurately on the different lugs of the bars.according to the code employed in translating the characters of the onemachine to the characters of the other. 1

Connected to the guide plate 17 for the operating rods 16 is'a bed plate20 carrying the nipples of Bowden cables 21 connected to the operatingmechanism of the perforating machine. In Fig. 1 one key 22 of theperforating machine only is illustrated together with its associatedmechanism which is shown asbeing of the'kind' described in thespecification filed with co-pending U. S. patent application Serial No.516,301 entitled Improvements in mechanism for perforating. statisticalcards filed in the names of Arthur Thomas and George Craig.

member for the typewriter key X.

As shown in Fig. 1 the Bowden cable 21 V abuts against a bell crank 23'co-operating with a pin 24- projecting from the key bar 25. The key bar25 has a downwardly extending lug 26 and when moved longitudinal- 1y bythe operation of the Bowden cable 21 disposes the lug 26 so that itregisters with a notch 27 in an intermediate bar 28, whereby said barcan rise until an eccentrically mounted disc 29 carried thereby engageswith a continuously rotating toothed roller 30. The rotation of thetoothed wheel 29 imparted thereto by the roller 30causes depres-' sionof the intermediate bar 28 and this bar then depresses a plunger 31connected to a Bowden cable 32 of which the other end actuates a bellcrank 33, thereby setting a set bar 34 for the corresponding punch.

The punch key may by suitable mechanism be operated from a special keyon the typvwriter added to that'machine for the urpose of operating theperforating mac ine ployed to automatically actuate the punch key ofthe'card perforating machine. There by without any special manualoperation on the master machine the carriage on the perforating machine,if constructed according to Thomas U. S. patent application Serial No.419,974, new l at-ent No. 1,858,174, is returned to initial positionthereby clearing th at machine and resetting connected machine.

In such form of typewriter machines star type is provided with actuatingmechanism exactly the same as any other type, that is to say, anintermediate lever, of which the arm. disposed to engage the roller isdepressed by the totalizer, there beingno key for operating the startype. Thereby, as result of a correct clearance of the totaliner thestar type intermediate lever is rocked through the agency of the rollerand its type bar brought into operative relation with the platen of themachine. In accordance with this invention the intermediate lever may beprovidedwith an extension in the same manner as intermediate levers ofthe alphabetical keys according to this invention, which extension isoperated with a push rod (see Fig. 1) suitably connected by a bar in thetranslating device for operating the punch key, thereby a simultaneousreturn of the carriage on the master and servant machines is obtained.

The connection between the intermediate lever for the star type bar andthe carriage return mechanism in the punching machine is illustrated inFigure 1, in which the push rod peratcd by the extension of the startype lever is indicated at and abuts against a hinged member 36, whichis similar to the hinged member 13. This hinged member does not co-actwith one of the parallel bars 14., but bears against one arn'i 37 of abell crank pivoted on a vertical 38. The other arm 39 of this bell crankabuts against a collar 40 on a rod 41, of which one end co-operates witha Bowden cable 42. Thus when the typewriter accumulators are cleared thestar type mechanism comes into operation and the push rod 35 isactuated, thereby turning the hinged member 36 in an anti-clock wisedirection about its pivot, and causing arm 39 of the bell crank to pushthe collar 40 together with the rod 4'? to the in Fig. 1..therebyactuating the Bowden cable 42, whichin turn causes the operationof the punches and simultaneously the return of the rod 16 is inalignment with the parallel 14a, or on the other hand, the pin 160.- canbe moved in to the other arm of the slot 167),- in which case nomovement will be transmitted to the rod 16 when the parallel bar 14 isactuated. The rod 16 and the parallel bar 1460 are in the nature of atoggle, which when the rods 16 and bars 14a are in alignment, forms aconnection between the master machine and the servant machine, but whenthe inner end of the rod 16 carrying the pin 16a is moved into the otherarm of the slot 16?), the movement oi the bell crank 15 produced bydisplacement of the bar 14 on depression of a key in the master machineis idle as regards transmission to the servant' machine. Thisdisplacement of the pins 16a can be eii ected by an automatic controlsuitably disposed for disconnecting the translating device, so that themaster and servant machine can work independently;

the perforating machine is usually only required to operate for a partof the travel of the typewriter carriage, this disengaging mechanism isconveniently controlled by the typewriter carriage. To this end ll theopcrating rods are engaged by a. shutteror hinged flap 44 pivoted on arod 45 and serving when rocked to move all the rods 16 into alignmentwith the parallel bars 14a. A short arm 46 is attached to the rod 45carrying the shutter 44 and this short arm 46 is connected by means of alink 47 to an arm 48 mounted on a spindle. 49 of which the other endcarries an arm 50 having mounted thereon a pin 51 which engages with acam track 52 in the form of a bar on the carriage of the typewriter.This cam track is provided with recesses 53 disposed at intervals alongits length and as the carriage travels the pin on the arm 50 will enterthe recesses under the action of a spring 54 attached to the arm 46 onthe shutter spindle 45. The upward movement of the arm 50 caused therebypermits the spring 54 to rotate the shutter and thereby move the rods 16out of alignment witn the bars 140. thereby disconnectin the translatingdevice.

The cam track or bar 52 is removable so that cam tracks of differentcontours may be used and to thisendthe bar is slotted at 5% and theseslots engage with pins 5212, thumb screws being arovided to secure thebar in place.

In order that the carriage of the perforating machine may be skipped atspecified points of travel of the carriage of the master machine,.thelatter is provided with latches or dogs of which one is shown at 55 inFig. 3.

A spindle 56 carries an arm 57 having an upturned nose 58 which engageswith the latch 55 as the carriage travels. The spindle 56 also carriesalong downwardly depending lever 59 of which the lower end abuts againsta collar 60 on a push rod 61 of which one end co-operates with theBowden cable 62. As the carriage travels towards the right in Fig. 8,the up-turned nose 58 on the lever 57 engages with the inclined surfaceof the dog 55 and the lever 57 is therefore depressed. Consequently, thelever 59 is turned and pushes the rod 61, thereby actuating the Bowdencable 62 which is connected to the space mechanism for the punchcarriage.

On the return of the typewriter carriage the vertical face of the dogengages with the up-turned nose 58 and is turned about its pivot 55aagainst the action of a spring (not shown) so as to swing clear of andover the nose 58. The rod 61 is returned by means of a spring 63.

In addition the back spacing mechanism-of the servant machine may becontrolled automatically from the master machine. To this end, a backspacing key 64 on the typewriter which is pivoted at 65 overlies a pin-66 on an arm 67 secured to a spindle v68, to the other end of which issecured a downwardly depending arm 69, which is forked at its lower endso as to straddle a push rod 70, to which is secured a collar 71 againstwhich abuts the forked lower end of the arm 69.

As shown in Fig. 4 the push'rod abuts against a hingedmember 72 whichactuates one of the parallel bars 14 in the same manner as the hingedmembers 13 actuate the parallel bars 14. A spring 7 3 abutting against acollar 74 of the push rod 70 serves to return the push rod. The parallelbar 14 which is actuated by the push rod 70 operates through a rod 16Bowden mechanism'21 connected to the back spacing mechanism of thepunching machine, which may be of any desired form.

The space bar on the typewriter may also be connect-ed to the spacemechanism on the punch carriage. To this end a push rod 75, shown inFigs. 4 and 6, may be employed'to actuate a hinged member 13 andparallel bar 14 in the manner already described. As shown in Fig. 6 thespace bar 7 6 of the type writer is mounted on two arms one at'e'achend, of which one 77 is shown in Fig. 6'.

, These arms are pivoted between their ends as at 7 8 and are connectedby a bail 7 9. Engaging with the upper edge of this bail is a hook 80 ona link 8101 which the lower end is pivoted to one arm 82 of a bell crankpivoted at 83. The other arm 84 of this bell crank is forkedat 85 so asto straddle the push rod and abut against a collar 86 secured thereto.Thus when the space bar? 6 is depressed the bail 79 is raised and liftsthe link 81, thereby turning the bell crank 82, 84 in a clockwisedirection, so as to push the rod 75 towards the right in Fig. 6, therebyactuating a corresponding hinged member and parallel in relation to thetranslation of the charac ters produced by operating alphabetical keysinto perforations on a statistical card. Such machines also have a rowof keys for operating type bars for printing members.

In the transmission of characters printing from these numeral keys on atypewriter machineto a perforating machine operating on a card havingonly two columns available for units items) it may be necessary toprovide for means for transmitting numerals into hundreds position. Inthe employment of statistical cards in this manner of which the columnshave rows numbered 0-9 it is usual to employthe space above the 0corresponding to the 12 and 11 positions as a means of' indicating thehundreds. For instance, the 12 position in the tens column is used torepresent one hundred, the 11 position in the same column to representtwo hundred and the 12 position in the units column to repre-' sentthree hundred and the 11 position in that column to represent fourhundred, whilst clearly the space above the 0 in such cards maybefurther divided up to show other numerals in the hundreds denominaition.As there are only two available columns on the card it is necessary tocut out the perforating machine when the. hundreds number key is beingdepressed in the typewriter, because there is not a hundreds column onthe card.

To this end the control shutter 44 previous)- ly referred to asoperating on the extensions 16 of the operating rods of the translatingdevice is controlled so that while the hundreds numeral is being typedthe translation is held up because there is not a'hundreds column on thecard. Then, on the printing of the tens number in the typewriter theshutter 44 must be released in order that a transmission from thisnumeral is made to theperforating machine.

As the machine is usually employed with .a partlcular card form theshutter 44 is conveniently controlled by the cam bar 52 for the purposeof holding up the translation when the hundreds key is depressed on thetypewriter.

It is now required to indicate on the card the hundreds number. To thisend the typewriter machine is provided with special keys correspondingto theO, 11, 12 positions on the card which are connected'todisplaceable bars which are added to and form part of the translatingdevice. These special keys may conveniently be referred to as the 0, 11,and 12 keys ofthe typewriter. As shown in Fig. 1 and more particulary inFig. 1A, each key is connected to its corresponding bar of thetranslating device by Bowden mechanism 87 through the agency of anoperating plunger 88 notched at 880 to engage over lever 89 pivoted onthe end of an operating rod 14a connected by a bell crank 15a to aparallel bar 14 carrying lugs 18 co-operating with levers 13. Thus, ifone of said special keys is depressed its lever 89 on the operating rodwill be rocked'clockwise as shown by "the arrow A in Fig. 1A.

At this end of all the operating rods 14a is a spring controlled pivotedflap 90 pivoted on a vertical axle 92, which is mounted in thetranslating device frame substantially at right angles to all the rods14a. The free edge of the flap 90 is arranged to work in elongated slots91 cut in each of the rods 14a, this free edge normally abutting theends 41a of, the slots 91 under the action of the spring controlling theflap 90, so that movement of any rod 14a from the keyboard of themachine rocks the flap 90 in the direction of the arrow B against thetension of its spring.

It will be seen that the elongated slots 91 ensure that other rods 14a,which are not moved, will not be operated by this movement of the flap90.

In order that the respective levers 89, when rocked, may co-operate withthe flap 90, they are each notched at 89a to egage the free edge of theflap and form thereby a connection between the flap 90 and the rod 14a,to which ,the lever 89 is pivoted. Consequently, if the flap 90 isrocked, this rod 14a will be moved to actuate the set bar 84 connectedthereto.

Thus, depression of one of the special keys on the typewriter, after thecam bar 52 has .held up the translation by rendering the translatingdevice inoperative when the hundreds digit is typed, and hasre-connected the translating device when the typewriter carriage is inthe tens position, will connect the associated bar 1464 to the flap 90with the result that when a tens key for typing a digit in the tenscolumn is operated, the rod 14a corresponding to the special key andthat corresponding to the particular tens akey', will be actuatedsimultaneously, so that both the hundreds and the tens digit will be setup together in the punching machine.

The present invention provides an effective means of connecting amachine of the Mer- -cedes relay operated type with a punch machine forstatistical cards and if a. perforating machine for statistical cards asdescribed in Thomas U. S. patent application Serial No. 419,974, nowPatent No. 1,858,174,

is employed there is a clearing of both machines as a result ofdepressing the special key provided according to the invention on theMercedes machine for actuating the punch key or its associatedoperatives in the punch machine. 7

The carriage in the Mercedes machine is automatically returned toinitial position and as described in Thomas U. S. patent application No.419,974, now Patent No, 1,858,- 174, operation of the punch key causesreturn of the carriage to initial position and in operation by actuationof what are known as the alphabetical keys of the keyboard, astatistical card is perforated without in any way interfering with thenumeral keys of the Mercedes which operate counters and print combined.Moreover, the device may be emn ployed for combining the operatives ofone machine with the operatives of another machine of a kind other thanthose which are controlled by a keyboard the essential feature being thesimplicity of the translator device which only involves as manyconnections as there are operatives in the two machines required to beconnected.

Further, it may be mentioned that the invention comprises also theemployment of two translating devices actuated from a single machinewhereby a plurality of machines are controlled from a single pair ofmachines, and in certain cases a single translator may be employed foroperating two sets of machines for instance, by employing both ends ofthe operating rods of the translator.
